Special issue of the International Conference on Computational and Experimental Science and Engineering (ICCESEN 2014) Determining the Optimum Heap Height Considering the Irrigation Rate and the Slope of Heap Bed Variations in Miduk Copper Mine

irrigation rates as well as variable conditions of permeability. From process view, approximately 75% of copper is recovered at irrigation rate of 8 l/hm 2 . Due to the significance of economic and process parameters in determining the optimum height of lifts, these parameters are simultaneously studied. The results are demonstrated that although the increase of irrigation rate and permeability can lead to more copper recovery in this mine, it will remarkably decrease the stable height of lifts. Moreover, changes in the bed slope will have a similar eect on the height of the lifts.
